Diversion engine problems biiiiig problem

[_Will_]

My diversion has serious engine issues, all of a sudden its over revving and theres noises, a kinda ticking noise up front and a muffled exhaust noise, both o right hand side left is fine engine and exhaust spot on, i also think there might be a small bit of oil leaking but im not to sure if its oil. anyone know whats wrong with it help greatly appreciated.

My XJ600N made two ticking noises. One was the clutch rattle which is a known problem. The other was the valve clearances needing adjusted.

Think a Yamaha dealer quoted me about £70-80 to check & adjust them. My mate's a mechanic and he showed me how to measure them. The same week that the valve depression tool (£14 online, not £80 from Yamaha) arrived I sold the bike, so never got round to sorting it out. I would describe the valve clearance noise as being like a sewing machine...but I don't know if that's helpful to you.

well lately ive had my list of problems, clutch went twice from lack of lubrication, recently theres a slapping noise at about 50 mph in top gear only thats like a sewing machine, this new noise is most apparent when im off the bike and revvin it slightly and gets worse the more u rev, top end has gone i get 90 at bout 7200 rpm when it was more like 100 top end at roughly 7000rpm, left exhaust sounds perfect but the right sounds like a harley lol so somethings wrong there and the ticking is from the right side of the engine.

Hmm...doesn't sound like valve clearances then. You hear them at idle speed, especially when cold, and the engine noise usually drowns them out by about 3-4000rpm Unless yours are really bad.

Yes the clutch is lubricated by oil but diversions suffer from a bad design, i have a very reputable garage i go to who is a family friend, he drilled holes in the clutch plate to help lubrication it often solves the problem and in my case it hasnt gone wrong again.
there was always rattle at idle but its a ticking with it thats new and the right exhaust sounds very strange, the top end i cant understand either i havent changed a thing yet ive lost the power i can describe it as its revving higher but not picking up the speed like it used to and throttle fully back it dosent reach the top end, i took it on a loooooooong straight where it would reach the 100mph(its restricted) but it struggled to even reach 90.

My Divvy will tick after I have taken her for a run and the engine is nice and hot. It's not a slapping noise and the normal engine noise drowns it out at speed. It just ticks away at about 4 beats a second at 1000 rpm so something needs adjusting I guess. Will look at getting the valve clearances checked.

What kind of oil leak do you have? Is it dribbling out of the breather pipe underneath? Most Divvys seem to do this. Since changing my exhaust (to a 4 to 1 system) the breather pipe now drops straight down in line with the wheels on mine, so I have to put a drip tray under the bike just in case to avoid getting oil on the tyres.

"ticking noise up front and a muffled exhaust noise" - Don't want to state the obvious, but are you sure your exhaust isn't blowing? Check your block-to-exhaust gaskets.

Actually, I need to check the seal on my downpipes as the gasets that came with the exhaust were too thick and the nuts would not bite into the threads with them in place. So I fitted the pipes without them. Anyone know where I can get a tube of "Liquid gasket" that will do the job and withstand exhaust heat? I want to drop the pipes off and re-seal them.

krebsy - did those gaskets look like they were made of a softish metal, that might kinda crush if you put enough pressure on them . I'd bet at least a small part of my shirt that your heat-related ticking is the exhaust blowing at the joint.

Try turning the studs out of the engine block a few of threads to get you going - but make sure you get them back to where they started before you finish up.

Exhaust blowing i hear money sounds, im gettin it checked at a garage tomorow(dont know much about the engine so dont want to start playin), hope it ent to bad as im doin a swindon-newcastle-lands end- john o groats-swindon trip soon and i need the bike healthy and wallet filled, Krebsy if it is my exhaust goin do u think its worth gettin a 4-2-1?

Well,

My Divvy suffered from the usual bottom collector rotting syndrome that affects all Divvy's and I had a pair of splits in the downpipes just beyond to collectors. The performance of the bike was suffering due to this (not to mention the niose) and I had patched it up repeatedly with putty and hose clips but it eventually just went.

A 4 to 1 system really is the best option IMHO. I was going to just swap the downpipes for 150 quid but figured that if the rear sections were dodgy then it would've been another 300+ quid for those. £350 all in for the complete system seemed to be the best option.

Was a pain to fit as the old system had been on for 30k miles and most of the bolts/nuts had rusted. I managed to hammer some sockets onto them and get them all undone but the studs would not budge from the engine. I'm loathed to drill those out and replace them as it would be too much work for me to do.

The new system was fitted (after re-cutting the threads on the bolts) with all the old nuts and after tightening it up it seems to be ok. I think the ticking is probably valve clearances and I'll check that out when I take the cover off to replace the gasket (which seems to be seeping a tiny bit of oil from time to time).

The system I put on was a Motad/Nexxus 4 to 1. Shop around, you can get it for 350 quid. The mid-range feels a lot better since putting it on but I think the carbs still need tuning to get a bit more welly out of the engine (Which will get me up to 100 before the acceleration rate drops off).

One benefit of the new pipes is that I can get at the oil filter without any problems. Previously it was an absolute pain to change the filter as there was no space to work in.

Downsides? The breather pipe (which dribbles oil from time to time on Divvys) had to be moved or it would've rested on the new rear section and either covered it in crud or melted. the tube now drops straight down so I have to use a drip tray if the bike is on the centre stand to avaoid getting oil on the tyres. Also, you may need to put a spacer (i.e. a thick washer) in when you fit the rear. On mine, the rear brake pedal was catching as the indent for it on the pipe was not lined up fully. That was fixed with a fat washer or two on the rear mount. I can still lock up the rear without the full travel of the pedal anyway, so I'm not too worried.

Set aside a weekend to get it done.

Here are some pics. (Note the GSX-R 1000 in black in the background.... )

just been to a garage, mechanic cant figure it out without taking apart , its booked in for next week but dosent sound good, right hand exhaust is goin, i kno that but the other stuff-not a clue at the moment neither has he. this bike trip is looking doubtful for me. could be time to sell the divvy been trying to convince my dad to give me his bmw r850r but no luck as yet lol, if anyone can think of anything it will help, i keep yall updated when i find out what is - if i do.

[_Will_]

[Radnor]

Keep an eye on this forum for used parts Link

I just got a right hand silencer for £40

[krebsy]

I've got a spare pair from the old exhaust but I've no idea how good they are.

yea booked in to find out what it is, turns out might be a few small problems that seems like a big one, its gettin a service aswell before i go on this trip, ive asked a few ppl who have seen it and theyve said it sounds like the ticking could be tappets ive noticed quite a lot of clutch rattle and the loss in performance could be the restrictors playing up, the silencer is going, krebsy how much you want for a right silencer?
its going in friday all day so hopefully the worst things will be sorted. might make a video of it running to post.
on another note my scooter is looking like its goin to be sold soon wahay one thing off my mind.

[_Will_]

Got it back from the garage today, split in gasket- they sealed that up, brake pads needed replacing, some bolt was loose- anyway ticking seems to be gone and it got a bit of a service(brake fluid oil filter, yet to see if it still struggles at top end, if it does im pondering over takin the restictors out and just bein careful, it seems to idle at around1700 rpm which is a bit higher and effects pullin off so its a bit pokier all in all it should be ok for this trip thanks for the help (not bad for 118 quid)
